Cet article décrit un émulateur d'évanouissement spatial basé sur le modèle de Clarke qui peut évaluer les caractéristiques de corrélation spatiale entre les signaux reçus par les antennes des combinés, y compris l'effet corps humain dans des environnements de propagation à trajets multiples émulés. Le modèle proposé est composé de diffuseurs, de déphaseurs et d'atténuateurs. Les diffuseurs sont situés à intervalles égaux sur la circonférence d'un cercle. Des déphaseurs et des atténuateurs dans un circuit de commande sont utilisés pour contrôler la phase et l'amplitude de chaque onde rayonnée par les diffuseurs afin d'émuler des environnements de propagation à trajets multiples, tels que la distribution Rayleigh ou Nakagami-Rice, à générer en leur centre. Dans cet article, la distance maximale entre les antennes de réception pouvant être utilisée pour évaluer les caractéristiques de corrélation spatiale entre les antennes a été étudiée expérimentalement. Les résultats des mesures montrent que 15 diffuseurs d'un rayon de 1.5 m suffisent pour évaluer les caractéristiques de corrélation spatiale dans un espacement des branches de 1.7 λ lorsque des antennes dipôles parallèles sont utilisées comme antennes de réception.

Abstract: This paper describes a spatial fading emulator based on Clarke's model that can evaluate spatial correlation characteristics between signals received by handset antennas including human-body effect under emulated multipath propagation environments. The proposed model is composed of scatterers, phase-shifters and attenuators. The scatterers are located at equal intervals on the circumference of a circle. Phase shifters and attenuators in a control circuit are used to control the phase and amplitude of each wave radiated from the scatterers in order to emulate multi-path propagation environments, such as Rayleigh or Nakagami-Rice distribution, to be generated at their center. In this paper, the maximum distance between receiving antennas that could be used to evaluate spatial correlation characteristics between antennas was investigated experimentally. The measurement results show that 15 scatterers with a radius of 1.5 m are sufficient to evaluate spatial correlation characteristics within the branch separation of 1.7 λ when parallel dipole antennas are used as receiving antennas.
